Today we have upgraded our Infrastructure VCenter with external PSC from 6.5 to 6.7 U2b and the upgrade did work out without problems. In the following we were using the converge tool (cli) to merge the psc again in the vcenter appliance. This has been working in the same asthonishing way as the upgrade.
To finish our upgrade we tried to decomission the obsolete external psc, but the script and the generated json file didn´t work. Everytime we tried to start it, we get the error "the PSC isn´t managed by this host.
We changed the json-file several times from the underlying vSphere esxi host to the new VCenter as managing device. As another try we were using another vSphere ESXi host and we migrated the PSC to this host, but we were getting everytime the same error.
